DNSmasq

Since nobody answered, I'll give something short.

ispCP Omega is designed to use BIND. If you want to run another solution, you'll have to either manage it yourself or modify the software to work with DNSMasq.

If you are going to use your machine as an authoritative DNS source for the hosted domains, you probably don't want to run DNSMasq anyway as it is not designed for that purpose.
